Max Ruth publishes on the instability of magnetic bion stripes in Phys. Rev. B

April 11, 2018

Stripe solitons are long solitary wave filaments which can be found in a variety of multidimensional contexts, e.g., in shallow water waves, Bose-Einstein condensates, and ferromagnetic materials. In a recent paper published in Physical Review B, a theory for modulations of a two-dimensional magnetic soliton filament, known as the bion...

Patrick Sprenger publishes on optical soliton tunneling in Phys. Rev. E

April 11, 2018

A widely celebrated feature of nonlinear optical materials is their support of optical solitons鈥攍ocalized, propagating pulses that maintain their shape over large distances. Light propagating in an optical fiber can be modeled effectively by the nonlinear Schr枚dinger equation (NLS), which can be cast into a hydrodynamic (fluid-like) system by a...

Vortex-antivortex proliferation in thin film ferromagnets highlighted in Physical Review B as editors' suggestion

April 5, 2017

Following the recent article on the dispersive hydrodynamic formulation of magnetization dynamics in thin film ferromagnets, Ezio Iacocca and Mark Hoefer explore the effect of finite-sized obstacles in this context. Thin film ferromagnets support uniform hydrodynamic states (UHSs) that can be parametrized by a fluid density and velocity. UHSs share...

Ezio Iacocca publishes the dispersive hydrodynamic formulation of thin film ferromagnets in Physical Review Letters

Jan. 5, 2017

Solid-state magnetic materials are intrinsically dynamic, stemming from the forces that act at the nanoscale and favor a macroscopic, collective order. In the case of a thin film ferromagnet, effectively a two dimensional magnetic medium, the equation describing its can be cast as a set of dispersive hydrodynamic equations. Remarkably,...
